The present invention provides an RFID tag that is very effective in preventing fraudulent uses. The RFID tag includes a base, an antenna pattern provided on the base, a breakdown pattern provided on the base, a circuit chip connected to both the antenna pattern and the breakdown pattern, and a cover that is bonded to the base in a strippable condition so as to cover the antenna pattern, the breakdown pattern and the circuit chip and is caused to come off together with all or a part of the breakdown pattern during stripping from the base. The breakdown pattern is transparent, or the cover conceals a remaining part of the breakdown pattern, or the breakdown pattern has a specific part that produces predetermined electrical properties and the cover conceals the specific part.

When crimping suspensions to carriage arms using a metal ball by applying ultrasonic vibration to a crimping tool, the suspensions can be crimped to the carriage arms without causing deformation to the suspensions and the like. A method of assembling a carriage assembly aligns attachment holes provided in front ends of carriage arms and crimping portions provided on suspensions to set the suspensions on the carriage arms and then presses a ball through crimping holes provided in the crimping portions while applying ultrasonic vibration to the crimping tool to crimp the suspensions to the carriage arms. When doing so, a ball, such as a ball whose surface has been subjected to a dimpling process, for which a load that acts on the ball when the ball passes through the crimping holes is low compared to a spherical ball is used to crimp the suspensions to the carriage arms.

The present invention relates to an RFID tag performing exchange of information with an external device without contact, and is to improve the resistance to bending while avoiding an increase in the thickness of the RFID tag. A circuit chip is bonded to a base portion of a base with a thermosetting adhesive. The base is folded, and an ultraviolet curing adhesive is applied on the circuit chip. The fold-back portions of the base are folded back onto the circuit chip, to which portions ultraviolet light is irradiated, as a result, both of the surfaces of the circuit chip are bonded to the base with the adhesives.

A method of assembling a carriage assembly and an assembling apparatus that uses the same are capable of suppressing fluctuation in the crimped (deformed) states of spacer portions when suspensions are attached to carriage arms. The method of assembling a carriage assembly aligns fitting holes 10a provided in carriage arms 10 with spacer holes 12b of suspensions 12 and then passes a ball 20 with a diameter equal to or greater than an inner diameter of the spacer holes 12b through the spacer holes 12b to crimp edge portions of the spacer holes 12b in spacer portions 12a and thereby attach the suspensions 12 to the carriage arms 10. While the ball 20 is being pressed and sandwiched from both sides of the spacer holes 12b by two pressure-applying members 40a, 40b and ultrasonic vibration is applied to the two pressure-applying members 40a, 40b, the two pressure applying members 40a, 40b are moved so as to pass the ball 20 through the spacer holes 12b.

An accelerometer for measuring the displacement of a magnet body using magnetic detecting elements is provided, the accelerometer having superior measurement accuracy by suppressing influence of a peripheral magnetic field. The accelerometer has detecting units each having a cantilever which is elastically deformed so as to rotate around a fixed end thereof, a magnet body provided at a free end of the cantilever, and a magnetic detecting head portion disposed outside the rotation region of the cantilever. In order to correct detection signals output from the magnetic detecting head portions, the accelerometer has peripheral magnetic field detecting portions for measuring a peripheral magnetic field acting on the magnetic detecting head portions and the magnet bodies.

In the method of forming a multi-piled bump, metal balls can be stably and securely piled so as to form the multi-piled bump having a prescribed height. The method of the present invention comprises the steps of: holding a metal wire by a capillary; sparking and melting the wire so as to form metal balls; piling a plurality of the metal balls with applying a load and ultrasonic vibrations thereto, and characterized in that a tail length of the metal wire, which is held by the capillary, is controlled to make a gap between a center of the metal wire and a center of the metal ball one half of a diameter of the metal wire or less.

A vehicle control unit and a vehicle equipped with the vehicle control unit are provided, the vehicle control unit being capable of preventing a shift change from being permitted in a direction opposite to a vehicle traveling direction caused by an erroneous operation of a shift lever during a traveling mode. In the vehicle control unit for controlling the vehicle on the basis of a shift range detecting unit configured to detect a shift range selected by a shift operation and a vehicle speed detecting unit configured to detect a vehicle speed, when the shift range detecting unit detects the shift range in a direction opposite to the vehicle traveling direction in a state where the vehicle speed detecting unit detects a vehicle speed not less than a first speed V1, the vehicle control is carried out so that a compulsory deceleration is carried out by means of a deceleration unit provided in the vehicle instead of permitting the shift change corresponding to the shift range, the shift change being desirably permitted when the vehicle speed detecting unit detects that the vehicle speed decreases down to a vehicle speed not more than the first speed V1.
